Continuing saga which you may have seen in my previous posts.
I was losing coolant but not from anywhere obvious, overheating quickly, coolant coming out of the overflow, lots of pressure if the radiator cap removed, could hear bubbling in exhaust etc. Suspected faulty head gasket so changed that. The gasket was shot. Put it back together and after some mucking around with a copper washer on an injector which stopped the injector seating properly, I have it back and running happily - except the temp gauge is still moving into the red after only 10 minutes or so. I have cleaned out the radiator, new 7psi cap, put in a new thermostat (which I have taken out at the moment as it is warm here). The radiator needs replacing as it copped a beating with excess pressure due to the head gasket issue. I have a new one on order but for the moment it is not leaking and is clean (can see through the fins etc and back flushed etc.
When the gauge has moved into the red (starts at cold and moves up over 10 mins or so) the engine is not hot - I can put my hand on the the radiator or the thermostat casing. Warm/hot but not burning. So could it be a faulty sensor?
I read some posts and tried removing the wire from the sensor and grounding it. The gauge moved hard right into the red. Before I fork out for a new sensor and the cost of getting it to Australia, I'm wondering about the electrics. I have the cluster of gauges not the old style individual ones. The temp gauge shares a fuse with the fuel gauge above it. The fuel gauge is stuck hard right on full. All this is recent.
I understand these temp sensors work on resistance but is there any way of testing if the sensor is faulty?
Any other thoughts on the fuel gauge??
Many thanks
